Abstract: 642,431. Vaporizers. JONSSON, G. E. V. Nov. 3, 1947, No. 29331. [Class 7 (iii)] [Also in Group XXVI] Vaporization of higher boiling-point fuels is obtained by heating the f u e 1 under sufficient pressure to ensure that it remains liquid and to such a temperature that it contains sufficient heat for complete vaporization when the pressure thereon is relieved, e.g. on injection into the engine cylinder or intake pipe. In Fig. 4 fuel which has been heated under pressure in a pipe 8 in the exhaust conduit is injected through a nozzle 6 into the cylinder 1, either during the induction or compression strokes, when complete vaporization of the fuel takes place. In a modification the injector 6 is located in the intake pipe adjacent the intake valve. Part of the fuel may be injected into the cylinder during the induction stroke for vaporization therein, the remainder being injected at the end of the compression stroke to initiate ignition. In Fig. 6 the fuel, heated under pressure, is injected continuously into a pressure below atmospheric maintained in a space 26 by a gas or steam injector 27, 28, the vaporized fuel being fed to an engine intake manifold, or an internal-combustion turbine. Cracking of the fuel during the heating may be facilitated by using catalysts. Reference has been directed by the Comptroller to Specifications 28847/09 and 15594/12, [both in Class 7 (iii)].

Abstract: 1278791 Agitating granular materials ARMSTRONG CORK CO 12 June 1969 29858/69 Heading B1C [Also in Divisions B4 B5 and H4] A mass of material having a parameter gradient therein in two or three dimensions, e.g. a dielectric constant gradient for a dielectric microwave Luneberg, Maxwell, or Eaton lens; or a colour gradation or pattern; is blended by placing a charge of a first material 15, e.g. of plain polystyrene beads of high dielectric constant, adjacent a surrounding charge 16 of a second material of complementary boundary shape, e.g. of aluminum sliver loaded polystyrene beads of lower dielectric constant, within a container 22 in which the charges are then stirred along a plurality of non-intersecting paths at least some whereof intersect both materials and blend these in concentrations dependent upon the varying relative proportions of each charge along different ones of the paths. The blended material may then be fused by steam heating. In the FIG 1B embodiment, a two dimensional Luneberg gradient is obtained by filling the first material into a tubular form 20 of cardioid section, which is located within a cylindrical mould 22 with the junction 0 of the cardioid lobes located along the mould axis The second material is filled between the form and mould 22, through screens 21a-21c which project radially of the form 20 and locate it within the mould 22. After raising the form 20 from out of the mould 22, the materials are blended along circular paths by slowly raising a slowly rotated circular wire mesh screen 23 upwardly through the mould by means either of an attached shaft 24 disposed along the mould axis, or by an attached drum located within the mould (22) outside the periphery of the charge 15. A further mesh screen may then be drawn through the materials to effect a randomising operation. A spherical dielectric gradient is obtained by superimposing over one open ended mould section (44b), another mould section (44a), Fig. 6C (not shown), closed at the bottom thereof by a planar cover which is then removed, and a circular stirring mesh then being gradually rotated and preferably vibrated as it is raised through the material contained in the superimposed moulds. The spherical lens may be turned out of the surrounding material after the cylindrical mass thereof has been fused. It is stated that the stirring paths may be elliptical.

An automatic sprinkler system includes a supply line 1, Fig. 18, embodying supply and master valves 2, 4 feeding sequentially operated section valves 5, each controlling a group of sprinklers 6, the actuation of which is determined by a selector valve 13, Fig. 3, depending from a panel 11 spaced from a front panel 10. The body of valve 13 may be injection moulded using a low density polyethylene plastic material such as eurethanes or neoprene; the valve body has a bore 14 with a reduced inner end 15 from which leads a drain port whilst into one diametral plane of the bore 14 open ports 16 each connected to one of the section valves 5, Fig. 18. Entering the bore 14 above the ports 16 are two further ports, and leading to the supply valve 2 by a line 3 and the other being connected to the master valve 4 through a line 7; the line 3 may be omitted. A shaft 20, Fig. 3, rotatable in the bore 14 has a socket part 21, Fig. 13, which may incorporate various arrangements of ports (Figs. 12, 17, not shown) which in conjunction with the body ports control the sprinklers. The remotely controlled valves 4 and 5, Fig. 18, may be of the normally open or closed type. When the selector valve rotates it opens the master valve 4 and whilst this valve remains open the valves 5 open and close in sequence; the selector valve has an " off " position and when it is so disposed the valves 4, 5 are inoperative. The shaft 20, Fig. 3, has a knob 42 which both indicates the shaft position on the panel 10, and enables the shaft to be manually actuated. On the panel 10 are as many yieldable and adjustable stems 44 as there are ports 16, each stem having a knob 45 with a quadrant engaging a stop quadrant 47 on the bushing 43 housing the stem 44; on the panel 10 around each knob is an " on " or running-time dial bearing suitable indicia. Attached to the shaft 20 is a gear 41 supporting a lever, one end of which has helical cam that coacts with the stems 44 whilst the other end abuts a reciprocable sleeve 53 on the shaft 20, the sleeve operating a " running- time " switch 54, Fig. 19. Mounted on panel 11 are high and low-speed drive motors 55, 56 both engaging a gear 41, Fig. 3, and the switch 54 is arranged so that when the lever is not contacted by any of the stems 44, the selector valve is driven by the high-speed motor 55; when one or more of the stems 44 contact the lever the drive is effected by the slow-speed motor; the sprinklers corresponding to the stems not so adjusted are inoperative. Control of the system may be effected by another motor 59 which drives hour and day dials, operating switches 62, 63, respectively, which when closed energize the high-speed motor 56.
